#### 6.2.1 Windows

Under Windows, you should add SICStus Prolog's and Java's DLL directories to your `%PATH%`. This will enable Windows library search method to locate all relevant DLLs. For SICStus, this is the same as where sicstus.exe is located, usually `C:\Program Files\SICStus Prolog VC10 3.12.11\bin`. For Java, it is usually C:\jdk1.3.1\jre\bin\hotspot (for JDK 1.6 it might be something like C:\Program Files\Java\jdk1.6.0_25\bin).

For example:

```     C:\> set PATH=C:\jdk1.3.1\jre\bin\hotspot;%PATH%
C:\> set PATH=C:\Program Files\SICStus Prolog VC10 3.12.11\bin;%PATH%
```

To make this change permanent you would use the `Advanced' tab in the `System' Control Panel. Consult your OS documentation for details.
